In this electronics basics episode we will have a closer look at motor encoders. Those can not only turn any motor into an awesome and satisfying input device for your projects; but can also turn any kind of motor into a kind of stepper motor. There are many different types of such encoders. So let me show you how they work, what they do and how you can use them. Let's get started ;-)

In this video we will be having a closer look at the first microcontroller board from Raspberry Pi, the Raspberry Pi Pico. The board is 1.5 years old but back then I was convinced that it was overrated. But things changed and nowadays I think it is a good Arduino alternative. So let me show you how to use the board and what exactly happened that made me change my mind. Let's get started!

In this video series I will show you how to build an electric motorized longboard from scratch. It can reach speeds up to 34km/h and travel up to 20km with a single charge. The estimated costs are around 300$ which makes it a good alternative to commercial solutions.

In this video we will have a look at the classic boost converter circuit and find a way to create a proper feedback based boost converter without a µC. Along the way I will show you how commercial boost converter keep their output voltage stable and how we can rebuild their circuit so achieve the same.

In this video I will tell you the basics about SPWM and show you how we can use it to create a pure sine wave. Afterwards we will have a closer look at the EGS002 which is a cheap SPWM driver board from China. I will create a DIY pure sine wave inverter with it and show you why it is not really a decent alternative to commercial inverters.
